Isocool improves cooling system at plastics manufacturing facility
Isocool
Cooling system upgrades and IsoFC energy saving device
Isocool enabled Really Useful Products, a plastics manufacturer, to save energy on its production line by upgrading its existing cooling system — which cost £33,000 a year to run — and retrofitting an IsoFC energy saving device.
Previously, the company’s mould circuit was cooled by a water chiller with a 316kW cooling capacity, and used an air blast cooler for its hydraulic oil cooling circuit. When the company began to experience problems with flow capacity and a suspected fault it contacted Isocool.
As Really Useful Products’ integrated tank and pump group were insufficient to meet its increased demands Isocool installed a weir tank, separate chiller and process pump sets. Large process pumps were installed on the mould cooling system, which has reduced the cycle times of the injection moulding process.
An IsoFC energy saving device was then retrofitted, which connects the mould and hydraulic cooling circuits through a heat exchanger unit. This facilitates energy transfer between the two systems without them mixing.
As a result of the improvements the client expects to have reduced cooling costs by more than £18,500 a year, and has experienced a 10 per cent increase in productivity.
